TO ALL WHOM IT MAY CONGERN:

Be it known that I,.Gnonos S'rAcKnoUs, of Mount-Washington, .n thecounty of Allegheny, and State of Pennsylvauia', have indented a. newand useful Improvement in a Device for Cutting Bread, Meat, Vegetables,

and other substances; and I do hereby declare that the following is afull, clear, and exact description thereof, which will enable othersskilled inthe art to make and use the saine, reference being had to theaccompanying drawings, forming part of this specification, in whichrFigure 1 is a sectional view of my invention, through the line y y, iig.2. i'.Pigure 2 is a crosssection of the invention; through the line :cz; of iig.' 1. Figure is a side view of the same. l

Similar letters of reference indicate like parts.` l The object o f thisinvention is to accomplish the cuttingor slicing of bread, meat,vegetables, and'other similar substances, in a rapid, `even, andexpeditious manner. l The cutting-mechanism is contained in a box', A AA C, having a sliding top, B, and hinged end D, the latter being hingedto the'bottom'of the box, as shown. l e

The slicing is accomplished by means cfa-horizontal knife, n, nhichvhsse vertical motion in slots-j, i n each side of the box. l i

The requisite motion is imparted to the knife by means of the exteriorrods ff, the ends of which are affixedto the sides of the box, withthei; front'ends inclined toward the bottom of the box, as shown.'

These rods are setent from the boxv by ineans of the projections h h,which latter serve to aix them .to

The npper ends of the rods are set out in a'. similai'manner, by whicharrangement the eyes e, forming part of the rod d d, and which work withloose contact upon the said inclincdrcds, are enabled to slide freely upand down the same, as the machine is operated'.

The front ends of .the rods d d are provided with eyes 1i, which workloosely ou pins 1c, projecting from the lateral edges of the hinged endD, whereby, when the said hinged 'en'd is swung open," as shown in redin'g. 1, therodsd d are brought down with'a parallel motion, asshown bythe red pcsitioirgf th rods in lig.

.These ro'ds slide freely through the eyes c c,at each end of the knifeor cutter a, and as the rods are raised i or lowered, the knife willalso be raised' or lowered, b'ylwhich operation the bread or othersubstance is sliced.

The movable partition b slides upon the guide-strips m m,iaixed to theinner sides loi' th'ebex fot` that pui*i pose, andthe partition b iscorrespondingly slotted, to work 'on the said guide-strips. l Thepartition b is actuated toward 4the knife bythe coiled' spring G orother suitable spring er springs; The partition b is retracted bymeansof the rod a, which is aflixed to the partitima'nd passes through theend,l C, as shown.

The terminal coils of the spring G are nixed to the partition, and ,tothe end, C, and the rod d passes within the said spring', as shown.

' To each side of the box are axed th'e vertical strips g g, one beingconvex,a`nd tb-: other correspondingly' concave, and as the eyes c c ofthe knife are in contact withthese strips throughout their upward anddcn'n ward movement, a lateral m'otion is thereby imparted to the knifeas it descends, inthe opersticn'of cutting, which lateral'motionconduees to the moreperfect slicing of tho substance. V f n A pin, o,limits the forward movement of the substance, as it is pnshednnder theknife, as each successive slice is cut off and removed, whereby theslices are all made o1 the'same thickness. This pin or its equivalentmay be so arranged as to be adjustable to or from the plane of the knfesmovement, so that .thinner er thicker slices may be obtained atpieasure. l l Therods ff may be substituted by similarly-inclinedplates, having slots for stud-pins projecting fromtbe rod d d to workin, or the sides of the box itself may be slotted in a similar manner.for the reception of the nid' Another modification may be made byaihxing hanged plate' ssut'sbly inclined, and providing the rodi d d`withsuitab1e open eyes to wor k on the `ilnnges; but in all thesemodifications, the principle of nnl inclined y surface, by which therods d d and the knife n 'are raised or lowered by the action of thehinged end, would be employed. i

The hinged end is pro yided with a handle, E, convenient for grasping inoperating the machine.. From what has been set forth, the operating ofthe-mechanism will be understood.

The sliding top Bv is withdrawn, and the partition b retracted, to placethe substance-to be out in the box. The rod a is then released, and thespring actuates the said substance Aagainst the pin o, as each slice is'cut and removed.

In order to bring the knife down to lthe bottom, the end, D, must beswung down horizontally. Having thus described my invention, I claim asnew, and desire to secure by Letters Pntent- 1. lThe inclinednetuating-surfaces ff, connected vwith Aa. hinged end, D, by rods d d,all substantially as described, for the purpose of operating the 'knifen, all as set forth. n Y Y 2.- The movable partition b, operated byspring-tension, substantially as and for thepurpose describcd, incombination with the inclined rodsff, hinged end D, and knife n, all asset forth.

3. The box A'A C, having a. sliding top, B, hinged end D, and slots7',.i n combination with the spring G, partition b,la.nd knife n, all assot forth. L I

4. The concave and convex strips g g, 'substantially as described, incombination with the inclined surface ff, rods d d, hinged end D, andknife n, for the purpose of imparting a lateral movement tothc'latteignH as set forth.

The above specicationof my invention signed by me, this 26th day of`March, 1868.`
